I know I'm new to the site , but can answer some questions, luggage is almost identical in size rear trunk does open from the side which is more convient. No vibration it's based on the vulcan line, I do not care for the belt drive prefer shaft drive, seat height is the same as the venture for driver a little lower for passenger. 37 mpg , $17,999.00 on the price. it is nice up close and personal weight is about the same aswell and I do like the 6th gear overdrive. I have owned a vulcan and never had an issue ,the warrenty should be 2 years though. In either case I'm sticking with the Royal ride I am very happy with it and do not see a reason to change , it still turns heads where ever we go.
